Radon Mitigation in Dublin, OH
Dublin is an affluent northwest suburb of Columbus in Franklin County, where indoor radon averages 4.8 pCi/L — above the EPA action level. The county's glaciated till and limestone bedrock allow radon to enter the area's full-basement homes. Dublin homeowners should test every two years, as even newer subdivisions over high-radon soils accumulate the gas.

Why Do Dublin Homes Have Elevated Radon?
Geology: Ohio's cold winters intensify the stack effect, drawing radon-laden soil gas up through foundation cracks, sumps, and slab penetrations. Indoor radon commonly tests higher in winter, so a cold-season short-term test or a long-term test gives the most reliable reading.
Permits: Ohio requires radon mitigation contractors to hold an Ohio Department of Health (ODH) radon license. Franklin County homeowners should verify the contractor's ODH license number and obtain post-mitigation testing to confirm levels fall below the 4 pCi/L action level.

How the calculator maps test results to EPA guidance
| Radon level (pCi/L) | Risk tier | EPA-aligned recommendation |
|---|---|---|
| 0.0 – 1.9 | Below average — low | No action needed. Re-test every 2 years or after major renovation. |
| 2.0 – 3.9 | Elevated — EPA "consider mitigating" | Consider mitigation, especially with smokers, children, or lower-level bedrooms. Run a long-term (90+ day) test for confirmation. |
| 4.0 or higher | EPA Action Level — fix the home | Install an active radon mitigation system. EPA recommends fixing the home as soon as practical. |

Ohio Residential Property Disclosure Act (Ohio Rev. Code § 5302.30) requires sellers to disclose any known radon test results to buyers. In practice, most Dublin real estate transactions now include a radon contingency in the purchase agreement — and given that 38% of Dublin homes test elevated, buyers are increasingly insisting on pre-closing mitigation when results exceed 4 pCi/L.
Our partner contractor network handles closing-timeline mitigations within typical 7–14 day windows, including post-mitigation verification testing to satisfy lender and inspector requirements.
Are Winter Radon Levels Higher in Dublin?
Yes. Dublin's cold winters intensify radon entry through the stack effect — heated indoor air rising creates negative pressure in basements that pulls soil gas into the home at higher rates than warmer climates. Dublin winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Dublin winters. If your Dublin home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
